Blockchain Makes the World Interested in Finance's Dullest Parts

Am I too mean to the idea of closed trusted blockchains run by consortia of banks? Really this is a perfectly heartwarming story:

This is where I would normally object that there is nothing magically blockchain-y about keeping a centralized database of swaps contracts. Like, you could just hire Axoni -- or Depository Trust Company for that matter -- to keep a list of who has what swaps, and when you agree on an amendment or whatever you could send it to Axoni to update. And Axoni could keep that list on its computers, and it could also have a web page where the bank participants could log in and see the list. The actual innovative benefits of blockchain -- a ledger without a trusted central party, permissionless access for anyone -- aren't priorities here, and so there's no need for the traditional annoyances of blockchain -- slow and energy-hungry multiparty verification of transactions, the inefficient redundancy of everyone keeping the list.
